[0001] The utility model relates to the technical field of drawer-type switch devices, in particular to a switch cabinet drawer and a mounting plate assembly thereof. Background Art

[0002] A low-voltage drawer cabinet is a relatively common switch cabinet. The drawers in the low-voltage drawer cabinet include a drawer frame, and a variety of different electrical components are installed in the drawer frame. In order to facilitate the installation of these electrical components, a vertical mounting plate is often fixedly installed on the bottom plate of the drawer frame, and a corresponding fixed connection structure is set on the mounting plate, so that electrical components such as molded case circuit breakers and current transformers can be installed thereon. An existing mounting plate, such as the drawer mounting plate disclosed in the Chinese utility model patent with authorization announcement number CN204696539U, is used to fix and connect the molded case circuit breaker by opening connection holes at specific positions on the plate surface. In this case, it is necessary to open multiple groups of mounting holes for different brands and models of the same electrical component on the plate surface for different electrical components. This results in a large number of openings on the mounting plate and a messy position distribution. Not only is it cumbersome and inconvenient to process the mounting plate, but it is also difficult to distinguish which electrical component these mounting holes are suitable for installing after the processing is completed.

[0037] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0038] The switch cabinet drawer of the present invention is improved over the existing switch cabinet drawer, mainly by improving the structure of the mounting plate. By arranging a special component mounting rack thereon, it can adapt to the installation of electrical components of different models and brands. While ensuring applicability, compared with the original method of opening a large number of adaptable fixed connection holes on the mounting plate, the processing is convenient, the electrical components can be easily distinguished from each other's mounting structures during installation, and the manufacturing and assembly efficiency is high.

[0039] Specifically, the component mounting bracket of the present invention is an X-shaped mounting bracket, which includes a pair of fixed plates rotatably mounted on a central rotating shaft. The two fixed plates cross at the central rotating shaft to form an X shape. Both ends of the two fixed plates are provided with connecting structures for fixing the electrical components. In this way, when adjusting the angle between the two fixed plates, the position of the connecting structure can be adjusted, thereby adapting to the fixed installation of electrical components of different models and brands.

[0040] This article introduces various embodiments of the switch cabinet drawer based on the above concept with reference to the accompanying drawings.

[0041] like Figure 1-4 As shown, in one embodiment, the switch cabinet drawer includes a drawer frame 1, and a mounting plate assembly 2 is fixedly mounted on the bottom plate 10 of the drawer frame 1, wherein the mounting plate assembly 2 includes a mounting plate, and the above-mentioned component mounting frame is mounted on the mounting plate. The structure of the mounting plate is similar to the drawer mounting plate structure of the prior art, such as Figure 5-8 As shown, the "J"-shaped frame structure is formed by bending sheet material multiple times. It includes a front panel 21 and a rear panel 22 that are spaced parallel to each other. The front and rear panels are connected at the top by a horizontal top wall. The front and rear panels are bent at both ends of the bottom position to form fixed foot plates 23, which are respectively bent toward the front and rear sides. The fixed foot plates 23 are fixedly connected to the bottom plate 10 of the drawer frame 1. The front panel 21 and the rear panel 22 are each provided with fixed connection holes 27 for fixing and installing electrical components. As can be clearly seen from the figure, these fixed connection holes 27 include circular holes and rectangular elongated holes. Of course, in some other embodiments, the mounting plate can also be an L-shaped plate, with the horizontal side 51 of the L-shaped plate fixedly connected to the bottom plate 10 of the drawer frame 1, and the vertical side 50 is used to fix and install electrical components.

[0042] The central axis of the component mounting frame is fixedly mounted on the mounting plate perpendicular to the plate surface of the mounting plate, and the paired fixing plates 4 are mounted on the central axis through the mounting holes in their respective middle positions, so that they can rotate around the central axis. The connection structure provided on the fixing plate 4 is a long connection hole 40 extending along its length direction. When an electrical component, such as a molded case circuit breaker 6, is connected, it can be connected to the electrical component by passing through a locking bolt or a locking screw through the long connection hole 40. The use of the long connection hole 40 as the connection structure can further increase the range of adjustment of the connection structure on the basis of the adjustable angle of the paired fixing plates 4, thereby being able to more flexibly adapt to the installation of electrical components of different models or brands. Of course, in some embodiments, it is also feasible for the connection structure to adopt a circular connection hole or a connection stud fixedly set on the fixing plate 4, which is also included in the protection scope of the present utility model.

[0043] When the component mounting bracket is mounted on the mounting plate, in order to save drawer space, the paired fixing plates 4 are often placed as close as possible to the front panel 21 of the mounting plate to reserve more drawer space on the front side of the component mounting bracket. When using either a round hole or a connecting long hole 40 as the connecting structure, it is necessary to use a locking bolt or a locking screw to achieve a locking connection between the fixing plates 4 and the electrical components. At this time, in order to avoid interference between the locking bolt or the locking screw and the mounting plate, in one embodiment, the mounting plate is provided with a bypass opening 26 at the swinging area corresponding to the connecting structure to avoid the locking bolt or the locking screw, etc., which is used to connect the electrical components and the fixing plates 4, so as to ultimately achieve the purpose of rationally utilizing space. Based on this, the above describes a mounting plate having a front panel 21 and a rear panel 22. For this mounting plate, the bypass opening 26 can be provided only on the front panel 21, i.e., the side panel close to the component mounting bracket. Of course, the bypass opening 26 can also be provided on both the front and rear panels 22. For mounting plates having only a single-layer vertical plate structure, the bypass opening 26 can be provided on the mounting plate of the single-layer vertical plate structure.

[0044] Based on the above design concept or embodiment, in one embodiment, as Figure 9-11 As shown, the front panel of the mounting plate has a shaft mounting hole 24. The central shaft of the component mounting bracket is a conventional bolt. Specifically, a connecting bolt 3 is installed in the shaft mounting hole 24, extending vertically through the mounting plate surface. A pair of fixing plates 4 are rotatably mounted onto the connecting bolt 3. The bolt head 31 of the connecting bolt 3 is located on the front side of the front panel 21. The other end of the connecting bolt 3 passes through the front panel 21 and the rear panel 22, extending to the rear side of the rear panel 22. The two paired fixing plates 4 are mounted onto the connecting bolt 3, positioned between the bolt head 31 and the front panel surface. The ends of the connecting bolts 3 extending to the rear side of the mounting plate are screwed with connecting nuts, thereby securing the connecting bolts 3 to the mounting plate. This assembly method of the component mounting bracket and the mounting plate is relatively simple and convenient for processing and material sourcing. Of course, other embodiments are not excluded, in which fixing studs are vertically welded to the mounting plate, extending to the front side of the front panel 21. The paired fixing plates 4 are rotatably mounted onto the fixing studs. The front ends of the fixing studs are screwed with anti-detachment nuts to prevent the paired fixing plates 4 from detaching from the fixing studs.

[0045] When the connecting bolt 3 introduced above is used as the central rotating shaft of the paired fixing plates 4, as a more preferred embodiment, the rod body 30 of the connecting bolt 3 has a smooth section near the bolt head 31, and the paired fixing plates 4 are mounted on the smooth section. This can ensure the coaxiality of the two fixing plates 4 and the central rotating shaft, and avoid directly mounting the fixing plates 4 on the threaded section. After a period of use, the external thread is worn, and radial movement occurs between the fixing plates 4 and the central rotating shaft, affecting the fixing effect of the component mounting frame on the electrical components fixed thereon.

[0046] Based on the above design concepts or embodiments, in one embodiment, an auxiliary support member is fixed to the mounting plate. The auxiliary support member is located on the lower side of the component mounting frame and can support the electrical components mounted on the component mounting frame, thereby ensuring that the electrical components have a better fixing effect. The auxiliary support member can have various structures, such as a group of support blocks fixedly installed on the mounting plate through fixed connection holes 27. The support blocks can be one or more and support the electrical components from the bottom. In one embodiment, Figure 2-4 as well as Figure 12 As shown, the auxiliary support member is an L-shaped plate, which is fixedly connected to the mounting plate via a vertical edge 50 and a horizontal edge 51 to support the electrical components, thereby providing the electrical components with a larger supporting surface and ensuring a better supporting effect.

[0047] Furthermore, to accommodate different models and brands of electrical components, in a preferred embodiment, the auxiliary support member is mounted on the mounting plate in a height-adjustable manner. Specifically, during manufacture, the mounting plate is provided with a group of vertically extending adjustment slots 25 (one or more can constitute a group). The auxiliary support member, formed of an L-shaped plate, is mounted on the mounting plate and vertically adjustable via connecting screws or bolt assemblies extending through its vertical edges 50 and each of the adjustment slots 25. Of course, in a simpler variation, the auxiliary support member can be provided with vertically extending slots, with threaded connectors extending through these slots and the connecting circular holes on the mounting plate to achieve height adjustment of the auxiliary support member and lock it in place.

[0048] The embodiment of the mounting plate assembly of the present invention has the same specific structure as the mounting plate assembly structure in the embodiment of the switch cabinet drawer introduced above, and will not be further described herein.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
